Abstract

The invention discloses an air conditioner control method and device. The method includes the steps of detecting currents of an electric heater of an air conditioner and controlling the operation state of the air conditioner according to the specified state of a relay and the detected currents, wherein the relay is used for controlling the electric heater. According to the air conditioner control method and device, the operation state of the air conditioner can be controlled through the specified state of the relay and the detected currents, the specified state of the relay is the state which the relay should be under, and the current state of the relay can be known through the currents, and accordingly real-time detection of the relay is achieved, the situation that when the relay breaks down, the electric heater and even the whole air conditioner cannot normally operate is avoided, and a guarantee is provided for normal operation of the whole air conditioner.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] In winter, frost is the main reason that affects the heating effect of heat pump air conditioners. When the outdoor ambient temperature is close to or lower than 0°C, the air conditioner often needs to be defrosted. In the limited defrosting time, the heat pump air conditioner only relies on the output heat of the whole unit itself to defrost, which takes a long time, and the heat of the air-conditioning indoor mechanism decreases or cannot be heated at all during this period. Therefore, additional heat needs to be added to defrost. [0003] At present, the method of directly heating the refrigerant with an electric heater can be used to defrost, and the electric heater device installed on the pipeline can convert electric energy into heat energy of the refrigerant, thereby increasing the heat ou...
